Abstract : The moisture content of laminated timbers in four climates of the United States and various use situations was measured quarterly over a 3-year period. The year-round national average moisture content for protected exterior exposure was 9 percent; for interior exposure, 8 percent. Unprotected exterior exposures and such special interior exposures and such special interior environments as swimming pools exhibited wide variations in moisture content. Designs to prevent wetting at joints and ends and to provide proper ventilation were effective in reducing the moisture content of timbers in these exposures. (Author)
